The goal of the proposed project is to test the effectiveness of an intervention (Connect4Health Engage) focused on motivating and guiding patients to use empirically supported, freely available online tools for weight loss. A randomized trial will be conducted in primary care clinics. Fifteen to twenty PCPs will be recruited, followed by 453 patients. Patients will complete either the 52-week Connect4Health Engage intervention or Connect4Health Discover, an educational control.

De-identified individual data will be shared with other researchers. Researchers will need to complete a Data Use Agreement.

Data will be made available within six months of completing data collection, or at the time of the first associated publication, whichever comes first.

The data and documentation will only be made available to users under a Data Use Agreement (DUA) that ensures commitments to using the data only for research purposes; to protecting identification of any individual subject; to securing the data using appropriate computer technology; and to destroying or returning the data to us after analyses are completed. To protect the privacy and confidentiality of participants and to ensure appropriate use of these data, the deidentified data will be shared in a restricted repository to be made available to qualified researchers who submit an application and execute a DUA with the appropriate participant protections. Consistent with our institution's IRB requirements, data will be available for up to five years following the study's completion.
